Surface/Material popping...

Recommended Posts

Hey there.

 

It seems that a lot of times (also in nearly all environment/landscape demos in the art_samples and also in indoor scenes like interior_sample)

there is a lot of surface popping-in going on. So after loading is finished and the scene is "live" you can see surfaces popping in.

Is there anything that can prevent this? I find this rather annoying...

 

(This is also true for terrain stuff where depending on camera angle / panning, stuff is popping in all the time.

Not sure if this is preventable though... Still also pretty annoying...)

 

Best,

tL.

Just cross-checked with a couple of other engines. Seems like this is very common...

At least with detail stuff popping in after loading is finished.

 

The only thing I noticed that  usually doesn't happen 

is the popping on camera angle/pan. (it does in one of them though)

There were only two  engines where both of these things

didn't happen...

 

So yeah, nevermind...

What you observe is basically mesh / textures streaming. Textures can take a lot of space on disk / GPU memory, so to speed-up loading times only cached textures displaying first.

Right now there is no control on the streaming behavior (you can't select which object should be always loaded and which objects should be loaded first), so this random objects loading can occur. You can also disable the streaming completely, that would result in massive spikes when new object will be in front of the camera.

To hide this popping in your final project you can wait for several frames for objects to be loaded completely and while this loading occurs you can draw your own custom loading screen.

Thanks!
